Warden Brian Boyd is after poachers who hunt bears and illegally sell their gall bladders on the black market. Later, after almost being hit head-on by a drunk driver, Boyd chases the man through the mountains, and eventually winds up capturing the man on foot. Warden Nick Buckler gets a call about a dead eagle and must perform a necropsy to determine that it was electrocuted. Next, Buckler gets a call from a rancher about a deer whose body is covered with debilitating tumors. He must euthanize the animal. Lieutenant John Nores and a team execute a search warrant on the house of suspected sturgeon poachers and arrest a husband and wife.
